" IMPROVEMENT rN M x 'Ne AND' MASHING. MACHINES.

Specification forming part of Letters Patent No. 17,Q5 5 dated December 11, 1877; application filed September 13,1877.

To all whom it inayroncern;

of Barfelde, Prussia, Germany,have invented a new and Improved Mashing Apparatus, of

which the followingisa specification: F

This invention relates to an-improvedappa ratus for mashing-and intermixing various substances such as may be used as food for game;

for distilling, brewingpurposes, for the commingling and proper reduction of paints, starch,paper, soap, and other materialin the various arts referredto. 1 a

The invention consists in the various details of construction hereinafter more fully pointed out.

In the accompanying drawing, Figure 1 is a side view, partly in section, and Fig. 2 a central transverse section, of my improved apparatus.

Similar letters of reference indicate corresponding parts in all the figures.

The letter A represents an annular drum, made of sheet metal or other suitable material, and mounted on a hollow axle, B, with which it is free to revolve, the said axle resting in suitable supports or bearings C D. The annular drum A is, by radial partitions, divided into four (more or less) steam-tight chambers, a b c d, which communicate, respectivelygvith the hollow axle B by pipes a, c, &c., which pipes also serve as braces, either alone or with other braces, to connect the drum A to its hub h.

The axle B isat one end connected to a stationary pipe, 0, which communicates with a suitable steam-generator, a stuffing-box, f, being provided at the junction of the pipes B e to prevent the escape of steam. Another stuffing-box, g, is placed to prevent the escape of steam at the end of the hub h of the drum.

By the arrangement above described steam can be admitted from the generator through the pipes e B and a c, &c., into the chambers Y a I) c 01, respectively, while the drum is revolving or when stationary.

The pipes a 0 &c., are provided with stopcocks, by which the steam can be shut off from or admitted to any or all of the chambers a b 0 cl. Each of these chambers is provided with a suitable man-hole or hand-hole for introducing the matter to be mashed and intermixed. These openings can be closed steam-tight by a covers 0 c 01?, made of appropriate con- J Be it known that I, WILHELM VON Signow,

struction. Each chamber should also be provided witha glass gage, a manometer, and an air cock, or their equivalents. 1

The masticatin g attachm enn-for masticating or cutting up the matter to be mashed or reduced, is applied to one side of the drum A, and consists of a toothed, ribbed, orv roughened wheel, F, hung on a spindle, 5, within a suitable case, G, which is rigidly attached to the drum A. The spindle z' is contained partly within the hollow hub of the drum, as clearly shown in the drawing, and a stuffing-box, 00, is placed at the end of said hub on the spindle i, to prevent the escape of steam. The spindle 11 is provided with a pulley or other device by which rotary motion may be imparted to the toothed wheel F, independent of the rotation of the drum.

Opposite to the grinding-wheel F are applied within the casing G four, more or less, toothed or ribbed segments lc ha a, between which'and the wheel F the mashing or masticating process is effected. The distance between the toothed segments Ic Mn a and the grindingwheel may be varied by screw-spindles and adjusting apparatus k l m a, so

that the degree to which matter introduced is to be ground, reduced, or broken, may be regulated thereby.

Each of the chambers a b c d is connected with the chamber G by a three-way cock, 0 q r, 850., one arm of each of said cocks communicating with its respective chamber, while the second arm communicates with the chamber G, and the third serves as a discharge.

To complete the description of the apparatus, it should be added'that the drum A may be slowly revolved by turning a handwheel, 1", which revolves a worm, s, that engages into the teeth of an annular toothed wheel, t, attached to the drum A; but other means for revolving the drum may be used.

The operation of the apparatus is as follows: One, two, or more of the chambers to b c d are filled with the matter to be mashed and intermixed. Steam or steam and water is then introduced into such chambers, and the same are afterward set in communication with the masticating attachment and with each other by properly adjusting their respective threeway cocks. The empty chambers are or may also be made to communicate with the masticating attachment and with the full chambers. The steam will now thoroughly soften the matter in the chambers, and will, when the three-way cocks have been opened, aided, if desired, by the gravity of the contents, force the same from the upper chambers into the masticating attachment, and thence into the empty lower chamber or chambers of the drum. The drum A may now be partly revolved to bring the filled chambers to the top,

and the operation can be repeated until the matter is thoroughly and properly mashed. While passing through the masticating apparatus, the wheel F is revolved, to properly reduce thecontents By filling the difi'erent chambers with difi'erent substances, and causing certain of the chambers to communicate with each other, through the masticating apparatus. the different substances contained in such chambers will be thoroughly intermixed, besides being reduced. The matter, after being properly mashed and intermixed, is discharged through the discharge-arms of the three-way cocks 0 q r, &c.

If it is desired to still more thoroughly mix the different materials contained within the chambers 00 b 0 d, the drum A may be continuouslyand rapidly rotated by an endless bers a b c d, &c., said chambers communicating by pipes a c, &c., with the axle B of the drum A, and by pipes o q 1', &c., with the mashing or masticating chamber G, substantially as and for the purpose herein shown and described.

2'. The combination of the drum A with the masticating drum G, masticating -wheel F, and one or more segments, k l m n, all so arranged that the drum A may be made to communicate directly with the masticating apparatus, substantially as specified.
